OpenWhisk is a serverless functions platform for building cloud applications.
OpenWhisk offers a rich programming model for creating serverless APIs from functions,
composing functions into serverless workflows, and connecting events to functions using rules and triggers.

### Quick Start
The easiest way to start using OpenWhisk is to install the "Standalone" OpenWhisk stack.
This is a full-featured OpenWhisk stack running as a Java process for convenience.
Serverless functions run within Docker containers. You will need [Docker](https://docs.docker.com/install),
[Java](https://java.com/en/download/help/download_options.xml) and [Node.js](https://nodejs.org) available on your machine.
To get started:
```
git clone https://github.com/apache/openwhisk.git
cd openwhisk
./gradlew core:standalone:bootRun
```
- When the OpenWhisk stack is up, it will open your browser to a functions [Playground](./docs/images/playground-ui.png),
typically served from http://localhost:3232. The Playground allows you create and run functions directly from your browser.
- To make use of all OpenWhisk features, you will need the OpenWhisk command line tool called
`wsk` which you can download from https://s.apache.org/openwhisk-cli-download.
Please refer to the [CLI configuration](./docs/cli.md) for additional details. Typically you
configure the CLI for Standalone OpenWhisk as follows:
```
wsk property set \
--apihost 'http://localhost:3233' \
--auth '23bc46b1-71f6-4ed5-8c54-816aa4f8c502:123zO3xZCLrMN6v2BKK1dXYFpXlPkccOFqm12CdAsMgRU4VrNZ9lyGVCGuMDGIwP'
```
- Standalone OpenWhisk can be configured to deploy additional capabilities when that is desirable.
Additional resources are available [here](./core/standalone/README.md).
### Deploy to Kubernetes
OpenWhisk can also be installed on a Kubernetes cluster. You can use
a managed Kubernetes cluster provisioned from a public cloud provider
(e.g., AKS, EKS, IKS, GKE), or a cluster you manage yourself.
Additionally for local development, OpenWhisk is compatible with Minikube,
and Kubernetes for Mac using the support built into Docker 18.06 (or higher).
To get started:
```
git clone https://github.com/apache/openwhisk-deploy-kube.git
```
Then follow the instructions in the [OpenWhisk on Kubernetes README.md](https://github.com/apache/openwhisk-deploy-kube/blob/master/README.md).

### Project Repository Structure
The OpenWhisk system is built from a [number of components](docs/dev/modules.md). The picture below groups the components by their GitHub repos. Please open issues for a component against the appropriate repo (if in doubt just open against the main openwhisk repo).
